Cyclopentenone Annulation of 2-Oxocycloalkane-1-carbonitriles

Phase‐transfer alkylation of the 2‐oxocycloalkane‐l‐carbonitriles 1a and 1b with ethyl 4‐bromo‐3‐methoxy‐2‐butenoate (2), followed by deprotection and base‐catalyzed cyclization gave the annulated cyclopentenones 5a and 5b, respectively, in high overall yields (Scheme 1). Stereoselective catalytic h...
